Fan damage to Radiator

angelobangelobMember
Know this topis was covered, but was wondering if anyone makes a fan shroud for the fluidyne radiator? I pulled my radiator so I could prep the area for moving the a/c condenser up front and to remove the fans from the radiator core and this is what I found. Luckily I was not leaking yet, but I will have to beef up the tubes that were damaged before putting it back together. I can't believe any vender or mechanic would use these zip ties on a radiator. sheesh.

Thanks for any leads on a shroud, or measurements and guage if I need to fab one up.

Nice piece of workmanship.

For those not as adept, Flexalite make a fan pair that come with a shroud with almost perfect for for the Pantera radiator, although you still have to mount it to you radiator. It used to be the 220 part #, but I think it has been superseded by the 420.

Johnny Woods found the Flexalite shroud to be a hinderance to cooling at extended periods over 150 mph and cut flaps that opened with air flow at high speed.

This was for a customer's car. He wanted me to use the Flexalite dual fan/shroud combo that Julian spoke of. This was what I came up with to mount it.


Thanks for the compliments. It worked out great!

I'm undecided between the flex-a-lite combo with brackets made like above or having a shroud made, cost is almost the same between the two. I was quoted by a local sheet metal shop to make one that I would have to cut out the fan holes once I settle on the fans at:

.040 anodized aluminum (3/64) - $110.00
.063 mill finish aluminum (1/16)- $ 95.00

Aside from the thickness, what is the difference in the above metal and what would be a better choice for a shroud?

Thanks,

Angelo,

If it's a wash cost wise, I'd go with the locally fabricated unit because;
1. Fans should be mounted at least 3/4 of an inch from the radiator or their cfm will be reduced. I had to mount my flexalite shroud with standoffs to achieve that.
2. Spal and Flexalite fans are available in individual higher cfm outputs than the flexalite shrouded unit offers at 2500 cfm.
3. If you find the shroud restrictive at high speed it's easy to remove some metal or drill aditional holes.

A third option is to buy your aluminum radiator from any of the vendors; they all have brackets for the Flexilite shroud. And Dennis Quella sells a radiator with his own fabricated aluminum shroud & fans already attached, and welded 90 degree hose tubes, which eliminates two more hose-clamp joints. Vendor radiators also include fan thermostats and (usually) a bottle of anti-corrosion fluid- necessary in some parts of the country with corrosive water. None of this is included (or even available) from Fly-by-Night Auto Parts.
